TCP/IP-32 3.11b NET LOGON to Domain Fails Across Router

The information in this article applies to:

• Microsoft Windows for Workgroups version 3.11
• Microsoft TCP/IP-32 for Windows for Workgroup, version 3.11b

SYMPTOMS

When a Windows for Workgroups 3.11 client running Microsoft TCP/IP-32 3.11b attempts to log on to a Windows NT domain, using NET LOGON command from the command prompt across routers. The attempt fails and the following warning message appears:

   You are logged on, but have not been validated by a server.

CAUSE

The logon fails because the NET LOGON command attempts to resolve the domain name by using only b-node broadcasts. A query request for the domain <1C> SMB is not sent to the WINS server, nor is the local LMHOSTS file parsed after the three b-node broadcasts for Logon request SMB fail.

This problem does not occur when the Windows for Workgroups client logs on to the domain using the Enterprise logon option under Control Panel Networks in Windows for Workgroups3.11.

SOLUTION The above problem is fixed by updating the following WFW 3.11 files from the NT Server 3.51 CD or NT 4.0 Server CD.

   NDIS.386
   NET.EXE 
   NET.MSG 
   NETAPI.DLL 
   NWNBLINK.386 
   VNETSUP.386  
   VREDIR.386   
   VSERVER.386

• Support for inter-network browsing (they allow browsing to Windows NT domains from subnets that have only Windows for Workgroups clients).
• A fix for problems using the NWLink protocol with the Ethernet_II frame type when connecting to a Windows NT Server.

WHEN USING the NT 3.5 Server CD take the following steps :

To work around this problem, either use Control Panel Network to log on or replace Microsoft TCP/IP-32 version 3.11b with version 3.11A.

NOTE: The TCP/IP-32 version 3.11A drivers can be found on the Windows NT 3.5 Server CD, in the CLIENTS\TCP32WFW\DISKS directory.

1. From the Network group, run Network Setup.

2. Choose the Drivers button.

   Under Network Drivers, you will see your Network Interface Card (NIC) and the network protocols used on that NIC.

3. Select TCP/IP-32 3.11b.

4. Choose the Setup button and write down all of your TCP/IP-32 3.11b configuration information.

5. Choose the Cancel button to return to the Network Drivers dialog box.

6. Choose the Remove button and then the Yes button to confirm.

7. Choose the Add Protocol button.

8. Select Unlisted or Updated Protocol and Choose the OK button.

9. In the Install Driver dialog box, enter the path to the TCP/IP-32 3.11 files.

   You should then see Microsoft TCP/IP-32 3.11 in the Unlisted or Updated Protocol dialog.

10. Choose the OK button.

        You should then see Microsoft TCP/IP-32 3.11 in the Network Drivers
        dialog box.
    

11. Choose the Setup button and configure TCP/IP-32 3.11 based on

        the information you wrote down in step 4.
    

12. Choose the Close button to exit the Network Divers dialog box.

13. Choose the OK button to exit the Network Setup dialog box.

        Setup will modify system files.
    

14. Choose the OK button.

        Network Setup prompts you to reboot.
    

15. Choose the Restart Computer button .
